Application filed September 8, 1925.

This invent-ion relates to new and useful improvements in nailing machines ot' the type usually employed in lumber or wood-woiking mills 'for nailing together window-frames and the like, or for nailing the blind stops to the ambs ot such frames, and more particularly relates to an improved marking attachment ior such a nailing machine adapted or use to make a guide mark or imprint upon the blind stop simultaneously as it is nailed to the jamb, -for the purpose of providing means for accurately locating or positioning the usual casing or facing of the window trame with relation thereto after the frame has been secured in place in the building structure.

ln "erecting new buildings considerable time is etten required to properly arrange or locate the window casings with relation to the janibs of the window trames, that they may be mounted in lparallel relation-substantially with the blind stopvor edge of the trame and with the proper offset with relation therea to. The method most commonly employed at `present for thus relatively locating and aligning the casings upon the trames, consists in manually placing guide-marks with a pencil or other device upon the outer `tace of the blind stop or edge of the trame on each side thereof, with which the inner edge of each casing is aligned before being nailed or secured in place. The jambs or trame edges are usually thus marked adjacent their upper and lower end-portionsltisthereiore desirable that means be provided whereby 4such manual marking of the trames may be dis pensed with, and whereby the edges of the frame may be automatically and accurately marked, without loss of time, during the process of manufacturing or'assembling the irame. y

The particular object of this invention, therefore, is to provide an improved marking attachment i'ora nailing machine of the above type whereby the edges of the frame jambe may be automatically marked simultaneously as the blind stop of the j amb is nailed thereto, thereby greatly simplifying and expediting the operation or work of mounting the casings upon the trames.

Other objects of the invention will appear from the following description and the ac` companying drawings and willbe pointed out in the annexed claims le the aeronepanying drawings there has Serial No. 55,115.

been disclosed a structure designed to carry out the objects oit the invention, but it is to he understood that the invention is not to be confined to the exact features shown, as various changes may be made within the scope ot' the claims which follow.

ln the accompanying drawings forming part ot this specilication: y

Figure l is a view in front elevation of a portion of a nailing machine showing my invention applied thereto;

Figure 2 is an enlarged detail view, partially in section, showing the marking device in engagement with the blind stop to make a mark thereon simultaneously as anail is being driven through it bythe nailing machine;

Figure 3 is an enlarged detail sectional view on the line 3-f3 `of Figure l, showing .the preferred manner oi mounting the markmg device upon a nailing machine;

` lFigure 4 is a sectional plan view on the line Meret Figure 2; and

Figure 5 is a perspective view of a `portion of a window iframe showing how the blind stop or edgeot the frame is marked to provide means tor aligning-and locating the casings thereon.

The form of nailing machine shown inthe Vaccompanying drawings is of the type employed in lumber or woodworking mills for nailing together windowtrames and the'like, and especially for nailing the blind stops to the ambs ot the frame. As shownin Figure l, this machine comprises a bed `6 having a frame or guide 7 mounted thereon against which the jamb 8 and blind-stop 9 may be seated preparatory to being nailed together, as shown'in Figures 2 and 3. A pair of supportingbars l1 and 12 are arranged over the bed 6 to provide `means for supporting the nailing boxes 13, which ,are adjustably mounted thereon so that thespacingbetween th'enails may be varied to suit the particular size ot the work being assembled thereon.

These supporting bars are mounted upon a suitable supporting means, not shown. The usual hammer bar 14 is mounted over the nailing boxes i3 and is adapted to be downwardly moved to the dotted line position shown in Figure 3 by a suitable operative mechanism not shown in the drawings.

nail tube 15 leads from each boX 13 to a suitable source et supply. The ahove disclosed unnecessary to describe `or illustrate it in and 4. This properly mechanism is old and it is therefore thought detail. Y i p Y Y Y A feature of this invention resides in the novel means Vprovided forv automatically marking the outer, face ofeach end-portion of the blind-stop l5 'with suitable guidemarks 16 simultaneously as the Vnailsl7 are driven through .the blind-stop 9 and into thejamb 8 during the operation of securing theV blind-stop thereto.

Such means preferably consists of adjustl ably mounting a'pair'of marking heads 2l upon the supporting bars lland l2 as shown in Figure 3. Each headmay be suitably secured to the supporting' bars by means of a clamp 22 having a screw 23 mounted therein in threadedengagement with the head 2 1 as shown. The heads Yare also provided with tongues2l`adapted to lit between Vthe supporting bars 1l and l2 soas to retain them "slide has its' lower end-portionformed to provide arelatively thin edge 26 which is' adapted to be forced downwardly into the face of the jamb or blind-stop as shown in Figures 2 and'3, for the purpose of producing the guide marks 16 against whichthe inner edge of the casing 27 may be placed as shown in Figure 5, when mounting the casing upon the win'dowframe. The u per end portion of theslide 24 is preferab y providedwith an elongated openingor slot28 in which'a coiled compression spring 29 is mounted, having its lower end seated upon the upper face of the head 2ll and a plate 3l secured to the head byV means of screws 32 as shown in Figuresj slide 24 in the guide 25. The upper end of the spring 29 is seated against ythe end of the' slot. 28 so that the spring constantly tends to exert an upward force against the slide 24 to normally hold it in the position shown in Figure3, wherein itV will be noted that the lower end of the slot is in engagement with a stopv lug 33 preferably integrally formedrwith the plate31 as shown. ,Ani adj Listing screw 34E-is mounted in the upper end-A portion of the slide bar 24; adapted to be en-V gaged by the lower face of the edge of the hammer bar Mas shown in Figure 2, thereby `forcing the slide 24 downwardly from the position'shown iny Figure 3 to that shown in y Figure 2.; A lock nut 35 is preferably provided upon the adjusting screw 34 to securely lockit in its adjusted position. By the employment Vof this novel marking plate functions to retain the device in connection with the nailing machine of the type above described, the outer face of the blin-dstop will be automaticallyvmarked at each end, without loss of time, simultane-Y ou'slyV as V.it Visrbeing secured to Vthe amb v19. By adjustably'mountingvthe marking heads upon the supporting bars il and l2'as above described, Vtheir relative positions thereon may be varied to properly space the guidemarks upon the face of the blindstops,`as particularlyv shown in Figure 5. Y

From the' foregoing, therefore, it will readily be noted thatthe operation of thus marking the'blind-stops to provide means for locat- Y ingv and aligning the casings thereonV will be accomplished simultaneously with the opera` tion ofnailing the blind-stop tothe jamb, thereby providing means for thus automatically" marking the Vstops without increasing thev cost of manufacturing thewindow frame and by thus marking the frames a considerableamount of time and labor will be saved in not having to mark'with a pencil or other device each window frame prior to mounting 'the casing thereon. The construction of the device is alsovery simple and inexpensive and is'so designed thatV it mayV readily and quickly. be mountedupon nailing machines of ordinary construction, and, when desired, may readily be removed therefrom'. Y
